Title: Miflex paper in oil caps
Post by: ochremoon on January 12, 2016, 09:55:29 AM
Anyone know anything about these caps? They look like they're modelled on Dueland cast to me.

Man there is a glut of caps around worth trying, but i have a draw full of discards, don't tempt me please, Don't know anything about these, but i will check them out.

Great to see look similar to duelunds

I don't like that they leak oil after a while though (Duelund Cast). This is one of the best and most expensive caps in the world so build quality should commensurate. Oh well, even the VSF got problem last time, I guess this is expected (?).

Those remind me of the caps Jimmy was playing with, same twisted lead outs...kinda.

Maybe a variation of them?

The ones he played with are sectional by the look, but otherwise, a similar look, more than others that i have seen.

I could be wrong.

I've just bought 0.1uf miflex caps for bypass purposes in my tube preamp. Will show pics when they are installed!

Interesting did you get the copper or aluminium. I love trying capacitors.

Mate wanted me to steal the signal early in his Rotel player passing it through some quality caps like I had done in my Marantz, the Rotel is a better implemented TDA1541 player than many of the cheaper ones, black gates throughout, .22uf decoupling caps around the DAC chip and a more symmetrical circuit from the DAC chip to the RCAs.

I should have snagged one of these instead of my CD65.

Anyway, used some 1uf Miflex Copper Paper Oil caps, only around 10 hours up so far but already starting to open up a little and more detail evident compared with first hour.

Will be interesting to see how they progress while I still have it with me. Edit: I know of one guy at least that says he likes these better than the Jupiter Copper's.

Data i am not a big fan of the Jupiter Copper's, the one i used had silver lead outs, good but not great. But its all so system dependent.

Hay, Steve, was just a reference, only one I had :)

While I thought Jupiters were alright when I used some, I much preferred Duelund Copper VSF caps, unfortunately very expensive now  :'(
I miss that rich layered bass and sweet mids the VSF's have  8)

I have some miflex to try too . Havent had time to install them yet .
  Developing my own pf range capacitors. 
     Very promising cost no object  to fill the  pf size void .
   Hopefully ready in a few months .

I have some .1uf KPCU-01 I was to use as by-passes on some Andyn Copper's in my CD player's output, won't get around to trying them for a couple of weeks now though.

The Miflex are in as bypasses over already run in Andyn Copper Foils in the CD-60. only around 15 hours on them but from the get go they removed the harshness from the character of the Andyn's, not that they were bad, just taken a step forward in a few ways having the Miflex in there. I'll wait for around 50+ hours before maybe other observations.

Edit: Not really able to speak on differences with the Miflex really, It's a different player than previously, I'd also need to be using a single cap same value of each to make a proper evaluation. Have also changed some resistors in my amp.

G'day Steve. The company I am working for now is selling hi end cable ties and heat shrink. We mainly sell to OEM and military. Time to upgrade me thinks?  ;D ;D

I removed the Miflex copper caps I had by passing the Andyn's, turns out the by pass was smearing the sound, over all much better with just the Andyn copper caps without them.

Kicking myself for putting them across the Andyn caps, sound is so much better without them  :o

Now, I wonder if Duelund's new JDM range being released will be more like the Cast or the VSF's, hope someone here reports after trying them  8)

Hi Bypassing caps is an old idea because most older vintage oil caps are not that good, so often the performance improved with a bypass, with the new stable of excellent caps bypassing just does not work for me, so i am not at all surprised

Just a couple of  comments  re bypassing . I dont   recomend bypassing in signal path unless its bypassing  electrolytics  such as the back  to back type in many  early cd players like the Marantz  cd 94 etc ,and its not perfect but still an improvement over the inferior electrolytic  on their own . , but you HAVE   to use a .01 uf  .  It may be only one decimal  point  but will make the difference from  being great to crap .    .Miflex dont make a .01 uf unfortunately  . In fact i did try their .02 uf cap as a bypass  and that didn't sound right either .Thats how  critical  it can be .  Secondly , many cheaper film caps can be a bit bright compared to a jupiter copper foil  for example  and could  tilt the  the upper frequencies up a bit . 
    Where bypassing works ,  is with electrolytics in power supplies . Only use a .01 uf  copper foil like Duelund  or  Jupiter ..  they have come down in price now  so no one needs to use an inferior .01 uf cap . 
    If you are using  a decent output  cap  no need to bypass in my opinion.  . My vsf caps in the 94 mk2  are not bypassed .
